REMOTE CONTROL FOR RADIO RECEIVING SETS Application filed October 28, 1930. Serial No. 491,786.

This invention relates to a remote control for radio receiving sets, and has for its object to provide, in a manner as hereinafter set forth, means whereby a radio receiving set can be controlled at a point remote therefrom for making the set active, for selectively locating broadcasting stations, for regulating the volume of the output or signals given off the set and to enable one to satisfactorily hear the output or signals at the remote point of control or at a point removed from the latter thus permitting of the using of the set without the necessity of being in the room where the set is arranged.

Briefly described the invention resides in the combining with a radio receiving set an electrically operated shifting mechanism for actuating in the desired direction the station finder element or elements of the set, an extension control for said mechanism operated at a point remote therefrom and from the set, an extension control for the volume control element of the set and with such eX- tension control operated at such remote point, an extension control for the pilot light or illuminable indicator circuit, designating when the set is active or inactive and with such extension control operated from such remote point, and an extension control for loud speakers and with such control operated from such remote point, said several controls being carried by a common panel therefor and extended from the latter to the receiving set and said shifting mechanism.

Al further object of the invention is to provide, in a manner as hereinafter set forth, a remote control for receiving sets including an electrically operated mechanism for operating the station finder means of the set and further with means for controllingthe direction of movement given to the station finder means and with such controlling means operated from a point remote from said mechanism and set.

Further objects of the invention are to provide, in a manner as hereinafter set forth, a remote control for radio receiving sets which is simple in its construction and arrangement, strong, durable, compact,

readily installed with respect to the set, thoroughly eficient in its use, conveniently operated, and inexpensive to manufacture.

With the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specically described, and illustrated in the accompanying drawings wherein is shown embodiments of the invention, but it is to be understood that changes, variations and modifications can be resorted to which fall Within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views Figure l is a diagrammatic view showing the adaptation of a remote control, in accordance with this invention in connection with a radio receiving set.

Figure 2 is a front elevation illustrating` the shifting means for the station finder of the receiving set.

Figure 3 is a rear elevation of the structure shown in Figure 2. V

Figure 4 is a front elevation of a panel common to the controlling elements for the several remote control means of the attachment.

A remote control attachment, in accordance with this invention for radio receiving sets includes a reduction gearing, an electric motor for driving the latter, and a shifting connection to the station finder means of the set and'which is operated from the reduction gearing. It is to be understood that the form of driving connection for operating the gearing from the motor can be as desired and one form by way of example is illustrated by Figure 3.

In Figure l of the drawings there is illustrated thereby diagrammatically a radio receiving set which is indicated generally at l and there is illustrated thereby diagrammatically a unit referred to generally at 2 9*) and which comprises a reduction gearing and the motor for driving the latter.

There is further illustrated in Figure 1 an extension control circuit 3 for reversing the direction of movement of the motor to provide for the shifting of the station finder means of the set in a clockwise and anticlockwise direction and with such extension control operated from a point remote from the set 1, as at 14. An extension control circuit for the volume control element of the set and with such extension control indicated at 5 and operated at a point remote from the set as at 6 and electrically connected with the volume control element of the set as at 7. An extension control circuit 8 for the pilot light or an illuminable indicator, designating when the set is active or inactive and with such extension control circuit operated at a point remote from the set 1 as at 9 and connected to the pilot light or illumina-ble indicator circuit 10 of the set 1 as at 11. The pilot light circuit 10 of the set is electrically connected with the latter as indicated at 12. An extension control circuit 13 for loud speakers and with such circuit 13 operated at a point remote from the receiving set 1 as at 15. A switch 16 is attached to the set 1 and from which leads the pilot light circuit 10. A power circuit 17 leads from a source to the switch 16 and a power circuit 18 leads from a source to the motor of the unit 2. The means for operat- -ing the circuit or circuits 3 is referred to at 14 and is in the form of a reversing switch for opening and closing such circuit or circuits and is carried by a panel 19. The means referred to as operating the circuit 5 and referred to at 6 is in the form of rheostat and is carried by panel 19. The means referred to as operating the circuit 8 and referred to at 9 is in the form of a switch and is carried by panel 19. rlhe means referred to for operating the circuit 13 and indicated at 15 is in the form of switches and is carried by the panel 19. The elements 6, 9, 14 and 15 are positioned on the rear face of panel 19. The circuit wires of the circuits 3, 5, 8 and 13 are housed in a cable 20.

Referring to Figures 2 and 3 of the drawings, 22 denotes a baseboard upon which a base plate 23 is mounted. Supported upon the plate 23 is the radio receiving set 1 and the shafts of the station finder means of the set are indicated at 24, 25 project from one side of set 1 and the projected ends of each of said shafts carry sprocket pinions 26. Below the sprocket pinions 26 and spaced therefrom is a stationary guide 27 which is secured to the set 1 and is disposed lengthwise thereof. Positioned on the base 1 and opposing that side of the base 1 which is not provided with the sprocket pinions 26 is a motor 28. Opposing one end of the set 1 'in spaced relation is a housing 29 in which is enclosed the reduction gearing of the unit 2, and such gearing includes a driving shaft and a power transmitting shaft 31. The shaft 30 at one end projects a substantial distance from the housing or casing 29 and carries on its projecting end a worm gear 32 which meshes with a worm 33 carried by the motor shaft 34. On the operation of the motor 28 the worm 33 meshing with the worm gear 32 will provide for the operation of the shaft 30 whereby the reduction gearing of the housing 29 will be operated and impart motion to shaft 31. The shaft 31 projects a substantial distance from that side of the housing 29 opposite from which the shaft 30 projectsl and shaft 31 carries on its projecting end a disk 35 provided with an eccentricallydisposed crank pin 36 to which is attached a crank 37, the latter being pivotally connected as at 38 to a reciprocatory rack bar 39 travelling on the guide 27 and meshing withv the sprocket pinions 26 for the purpose of rotating the shafts 24, 25 in a like direction simultaneously. The shaft 30 has its opposite end projecting from the housing 29, as at 40 and constitutes a guide or stop for the element 39. Figure 2 illustrates one form of shifting connection between the reduction gearing and the station finder means of the set 1. The reduction gearing reduces speed of the rack bar 39 to the desired extent and permits of the station finder means of the set 1 being revolved in either direction for the purpose of selecting a broadcasting station. The direction of operation of the reduction gearing is changed from a clockwise to an anti-clockwise direction by the controlling circuit 3 which associates with the motor 28 and acts to change the direction of operation of the motor shaft when desired. A support41 is mounted on the plate 23 for the motor 28. A housing or casing 42 may if desired enclose the elements 1, 28 and 29, as well as the baseboard 22.

The panel 19 has its outer face provided with suitable indicia 43, 44, 45 and 46 associated respectively with the elements 15, 9, 6 and 14. The indicium 43 is to indicate when the loud speakers are on or off. The indicium 44 is to indicate when the pilot-light vcircuit is on or 0E. The indicium 45 is to indicate the direction of the turn for decreasing or increasing the sound or rather the volume control and the indicium 46 is to indicate the advance or reverse with respect to the station finder means of the set 1.

The attachment as heretofore set forth will control the radio receiving set from any place in a room where the panel is placed, thus permitting the use of the radio without the necessity of going to the room where the radio is located. Further, if desired, the owner of the radio may provide himself with additional switches which may be controlled from the panel. A further advantage of the attachment is its relative lightness making it portable and easily connected to any place desired. The cost of the attachment is comparatively small, the owner of the radio, if he so desires may provide himself With a number of panels, which after being connected may function independently or with the other panels and may be used for any type of electrical radio.
